listMarketBook request limits

[jptrader]

Are there any undocumented changes to the weights of the market data request limits. I have found that increasing the PriceProjection.ExBestOffersOverride.bestPricesDep th could give a "TOO_MUCH_DATA" error. Could you please update the documentation on this (and possibly other changes to the weights).

Hi jptrader,

There haven't any recent changes to the market data request limit weightings.

If you are receiving the "TOO_MUCH_DATA", please provide a specific example of the request being sent so that we can check this for you.

Thanks

Neil

According to the documentation I should be able to get 40 markets for listMarketBook with EX_BEST_OFFERS. In the example below I call listMarketBook for 31 markets, and this works as expected. However, if I replace the "bestPricesDepth":3 with "bestPricesDepth":6, the API returns a TOO_MUCH_DATA error. My tests have indicated that increasing bestPricesDepth to 6 I get an extra weight of 3, by increasing to 9 another 3.

Best, JP

Hi Neil,

Were you able to check the example I sent for you. If not, here is another one. This is for an event on Sunday 6th, so you should just need to copy the request until then. I have specified EX_BEST_OFFERS, which has a weight of 5, so I should be able to get 40 markets. But when bestPricesDepth is set to 6, as in the example, I get a TOO_MUCH_DATA response (there are 31 markets in the request).

Kind regards, JP
